We've reviewed cold weather rectangular sleeping bags and want to share some information with you. Rectangular sleeping bags have an incredibly roomy design, so they are suitable for people who feel too claustrophobic by the tight mummy shape. With double zippers, they are perfect for sleeping two as you can zip two sleeping bags together. They accommodate varying sleeping positions, so if you move around a lot at night, you'll have the space and freedom to sleep in any position you choose. However, they are quite heavy, so they aren't convenient for when weight is a concern. Another downside is that these sleeping bags are less ideal for cold weather, creating more room inside which can weaken the bag's ability to keep you warm.

Cold weather sleeping bags prevent any heat loss, so you can have a successful winter camp-out. They feature draft tubes, which run behind the zipper to help keep warm air from escaping. They are commonly designed with a draft collar, so you can move around at night without worrying about cold air pockets. These sleeping bags are more often than not made with feather down, so they have an excellent warmth-to-weight ratio.
